FIGURE 5.

Increased drought tolerance in N22oe plants. (A–D) Phenotype of the N22oe and WT seedlings at different stages during the drought stress experiments. The N22oe seedlings were grown in barrels each with WT seedlings as a control. (E) Survival ratios of the N22oe and WT plants at 12 days after re-watering. (F) Growth biomass of the seedlings after drought stress treatment. Data presented in (E,F) are the mean ± SD from three independent experiments and different letters above the columns indicate significant differences at p ≤ 0.05 level.
